2 residences one well; Pump RUNS constantly

Hello forum. My name is James and I have a few questions to ask. Most recently I moved into a house that obtains water through a deep well system that stopped working after a year of living here. The system was replaced with same characteristics except the pressure tank.{100ft. well; new 1/2 horse power pump(Berkley); new avc 42gal. tank(avc is in middle of tank in the 1 1/4inch outlet, not the top 1/4inch outlet hole); new foot vave that is 25ft. below the static water level}.
The "meat" of my issue is this: The neighbors that live on the plat behind me were building their house themselves, and needed water(they have NO deep well, septic system or a registered county address). So my household allowed them to use our outside faucet to have some water through @60yards of connected hose. They then burried the long hose 4inches underground for the total length of the connection. I left the outside faucet on to be considerate of their needs at the time. Note this was to only be needed until their well was dug. It has been over 3 months. They have not begun to dig for a well, and I noticed the pump is cycling every 1minutes & 18secs. I cut off the out side faucet and not only did it not cycle for over 40minutes it held it's pressure at 50psi(set for 30/50). This let me know that something was wrong. Went next door and found out they had a leak in the hose were it connects to their house. I found out they hooked the end of the hose from my house to their house through a inlet faucet conversion that flows water through thier sinks (2 so far). They also have a splitter that has another hose on it the is draped through their bathroom window that they are using to fill their toilet bowl tank so they can flush it. But I thought how can they be flushing without a county sewage hook-up line, or a septic system. EUREKA!! At the end of our 3/4 acre property they dug a trench @ 1ft. deep, and put a big pvc pipe from under their house(near the bathroom), ran this pipe @ 40ft. and broke out a hole
in the top of our 2nd cylinder(1ft.under surface) in our septic system. Who do these people think they are? When questioned about this they say our drainfields run on their property, and if we don't want to get in trouble and to have to get them pulled up(costing $15,000) I better be cool. But every thing in my residence is up to code and on county records.
So now my pump keeps running non-stop every minute or so. The neighbor says "he has a leak and don't worry about it, deep well pumps can handle running all day, how do you think people water their lawns"? I'm confused about my rights and my newly installed pump. He is saying I should stop worrying because the pump will be fine, and if it goes up he will replace the pump.
The reason I have not cut off our outside faucet is because of what he says about the drainfeilds on his property. I don't want the fines or whatever that he is claiming.
IS THERE ANY THING I CAN DO TO STOP THE PUMP FROM CONSTANTLY RUNNING BESIDES CUTTING THE OUTSIDE FAUCET OFF? ANY MANUAL ADJUSTMENTS? ANY EQUIPMENT PARTS I CAN INSTALL? CAN MY PUMP BURN UP BEING 1/2HP AND 4 MONTHS OLD? WHERE CAN I FIND OUT ABOUT MY RIGHTS? CAN A PUMP HANDLE 2 RESIDENCES? CAN THE WELL RUN DRY BECAUSE OF CONSTANT RUNNING OF PUMP?

I don't know about the fields being on his property, but if you bought your place and did a title search etc. If this is true, you should be able to go back on the title company.

I think this guy is just blowing smoke and if it were me, I would have cut the hose a long time ago.

Give him an inch and he'll take a mile.

If it were me, I would call code inforcement in your county. These people can't have a CO to live in that house which means they don't have power except for maybe a temporary pole for building purposes. Without a CO they can't live there. And the code folks would probably not look kindly at what is going on.

Finally I had had enough! My pump had been cycle every 48seconds{on/Off} for the last 28 hours. The pump was extremely HOT and began to click after the "cut-off" pressure was reached. I cut the discharge off to let it cool down, and hoped they would then fix their leak after informing them I had to cut the water. They never returned my message and the next day THEY PUT A FOR SALE SIGN UP. tHE FUNNY THING ABOUT IT IS THE ADDRESS THEY ARE POSTING NEVER AND STILL DOES NOT EXIST. i FOUND OUT THEIR EASEMENT WAS ASSIGNED 20YRS. AGO TO ORIGINAL OWNER, BUT THE EASEMENT IS ONLY 4MONTHS OLD. Records department does not have plat on record for having an address. They don't even have a mailbox or #'s on the house. Will keep forum posted THANKS GUYS!!
P.S.
What was the clicking noise coming from the PUMP after "cut-off" pressure was reached on the tank (Kinda' was a creeking/clicking noise 2secs. long)?

Pump has gone back to it's original status. Pressure is holding, no more clicking after "cut-off" is reached. On the rest of the situation with neighbors, they still have the FOR SALE BY OWNER sign up. CODE ENFORCEMENT has not got involved yet to my knowledge. I have seen two big white DODGE trucks pull up and park, then pull off. They pulled up in there "suppose to be easement" about twenty feet then left. Note: Guys I live on a dead-end street that has 11 houses on it . My house is the last house at the end. Their lot is behind me. Thank you TERRY and BOB big help. This forum is "gem" to us novices!

Hello Forum,
It has been a while since I kept you all posted. Here it is:
1) The County Code Enforcement where I reside posted a "STOP WORK ORDER" in the paper for the "so-called" neighbors who still don't have an address! (Without any of my involvement at all)
2) They also were given a personal notice in hand!,(However the County does not know they live there with sinks, a bed etc.. The County has not been inside to my knowledge).
3) They have not had any source of water or electric to date.
4) The "FOR SALE BY OWNER" signs have been taken down!
5) State officials in white pick-ups have been seen canvassing the street where I reside several times!
6) They have been using a generator for electricity. The generator is well hid from on-lookers from the street. They block the windows with cardboard, and hide the one vehicle behind the back of the dwelling when they are there!
7) They still are living there, only after 12am do they come in. They put cardboard in the windows so you can't see the lamp and T.V..
8) Checking Court, State and County Records and Archives, these are the things that are unofficial or not registered to date:
A) their "easement"
B) their building plan & envelope
C) their electricity & water utilities
D) their "zoning" (status:non-residential)
E) No Perc testing
F) No surveys concerning their newly aquired lot since 1964.
Thank You guys for all your pro-support. My pump and well system are doing excellent since terminating the hose connection! Will post PICTURES OF THIS WHOLE EVENT showing them building their dwelling from start to finish, before and after shots, pump and tank shots, all characteristics to this event as it still unfolds!
Will keep posted!
